Letters Patent No. 113,860, dated April 18, 1871.

IMPROVEMENT IN LUBRICATORS FOR JOURNALS The Schedule referred to inthese Letters Patent and making part of the same.

I, PATRICK S. DEvLAN, of Jersey City, in the county of Hudson and Stateof New Jersey, have invented certain Improvements in Self- LubricatingJournal-Bearing, of which the following is a specification.

The nature of my invention consists ofrone or more pieces of felt orother textile fabric combined and arranged in cross-openings which runfrom the under edges of the journal-bearing through the same and abovethe journal, the ends of the felt passing down over each side of thejournal and resting on the bottom of the box, so as to take up the oilfor distributing it upon the journal; the oil passes up the felt bycapillary attraction, and is supplied to one or more plugs of felt orother brous or porous material connecting with the wearing' surface of'the bearing, whence it passes onto the journal.

The construction and operation of the lubricating device will beunderstood by the following description.

In the accompanying drawing, which makes a part of this specificationFigure 1 is a longitudinal section of a journal-bearing of a railroadcar with pieces of felt B in connection therewith. v

Figure 2 is a cross-section of the same and a journal in connectiontherewith taken at the line xa: of 1.

gFigure 3 is a cross-section of the box without the felt and journal atthe line y y of iig. 1.

Like letters in all the figures indicate the same arts. p Ais ajournal-bearing, which has cross-openings a that are seen clearly inh'g. 3.

In each opening a piece of felt or other fibrous fabric is placed, theends of which hang down each side of the journal C and lie on the bottomof the box.

lhere is a hole, b, in connection with each opening a, which is filledwith brous or porous material that is brought into contact with thejournal O.

Other analagous means may be used to make the connection between thelubricating strips and the wearing surface of the bearing, or the stripitself may be brought into contact with the journal by passing itthrough a suitable opening.

The oil, beingr taken up by the ends of the pieces of felt B, isconveyed up to the plugs D, which distribute it upon the journals as thelatter revolves.

The inner sides of the pieces B lying against the sides of the journal,as'seen in fig. 2, also distribute a quantity of oil upon the same.Hence an even and ample supply of oil is distributed upon the journal inits revolutions. A

I do not claim, broadly, the use of a strip or strips of felt, or otherequivalent material, for supplyingl oil to journal-bearings, as such afeature exists in other lubricators.

What I claim as my invention, and desire to secure by Letters Patent, is

The transverse openings athrough the body of the bearing, and theconnected holes b, in combination with the absorbent strips B, whichtouch the journal and lubricate it at points x x', and plugs D, arrangedand operating in relation to the journal C and oilreservoirsubstantially as described.

In testimony that the above is my invention I have hereunto set my handand axed my seal this 12th day of December, 1870.
